The present defigures; the car may be of anyusual and apvice is intended and designed for the purproved constructionof that type having a 70 pose of admitting air into a room, or comdecksash 7 to which the ventilator is directly partment and is ordinarily,though not attached. The ventilator comprises a flange necessarily, usedin connection with some or attaching plate 8 for securing it to theprovision for the outlet or exhaust of the decksash which is cut away at9 for the pas.-

Anumber of disadvantages sage of air therefrom into thecar, the cut- 75 have been found in connection with the inaway portionbeing in use in register with a take ventilators heretofore in use,among similarcut-away section of the sash.

Preferably 5 cumulation ofsuch materials. It is the obthese parts are all made' of sheet metalject of my invention to construct a ventilator though any materialsuitable for the purpose which furnishes a large volume of air from maybe used. The bottom plate. 6, as shown which the dirt, etc., is screenedand 'sepamore particularly in Fig. 2, is bent-into two 3 rated, andprovides for automatically getcurved wings or sections 12, 13 which meetting rid of the latter. In the accompanying centrally of the plate in aridge 14. and fall drawings and in the following specification awayuponopposite sides thereof forming I have disclosed two embodiments ofmy indeflectors either of which is active according vention which difierin respects which will to the direction of the air current.

It is tobe understood, howscribed. Thetop plate 11 is bent downwardly ever, that my invention is not limitedto and inwardly at its opposite ends to form these specific forms whichare shown and dethe deflectors 15, 16 which extend below the scribed indetail for the purpose of exemplilevel of the opening through the flangeplate Iication only, but itsscope isd'etermined by and to about thelevel of the ridge or apex thefollowing claims in which I have 'enof thebottom plate. deavored. to distinguish the invention from With the carmoving in the direction of the prior art so far as known to me without,the arrow A, Fig. 2, or in case of a sta- 59 however, relinquishing anypart thereof. tionary construction with the wind blowing In theaccompanying drawings Figure 1 in the opposite direction, air is caused"to is a perspective of so much of a car body as flow in the directionof the arrows B, Fig. 2, is necessary to understand my invention againstthe plate 13 by which it is deflected with the latter applied theretoFig. 2 a verupwardly and through the opening in the 55 ticallongitudinal section of the car body flange plate into the car.

Any dirt, leaves, snow or foreignmatter striking upon the entering section 13 of the bottom plate isretarded in its motion and in case the the same and drops over the ridgeor apex 14 upon the other side where it is carried away by that portionof the air current which spills over the ridge and escapes as set forthabove; and also any foreign matter which by-reason of any unusualstrength of the air current is carried upward beyond the ridge dropsbeyond the same, owing to air current and escapes. Thus thereis providedan ample volume of fresh air which is freed from heavy impurities andenters the car gently by reason of its changes in direction and its pathand without suflicient violence to be injurious to the occupants. Asshown in Fig. 3 the wall of the car is double at this point though thisdoes not materially affect the ventilator structure, and within the caris provided with a closure or damper 17 for the opening 17 carr ing apawl 18 coacting with the rack 19 by means-of which the position of thedamper may be regulated.

In function and operation the modifica- Figs. 4, v5 and 6 issubstanidentical with that described above, but it is somewhat changedin construction toadapt it to be used on the/curved roof of a so-calledturtle deck car. In this modiform to the shape of. that portion of theroof 7 to, which it is applied and cutaway at 9, the opening beingarranged whenin use in registry with a similar opening inthe roof of'thecar. \Vhen the lathollow, as shown in Fig. "6, the opening in the flangeplate is provided with a boxing 19 1 wall of the'roof to the other andis covered i by a perforated plate 20. Thefront vand rear ends oftheventilator casing are partially closed by end osite sides of "theplates, 22, 22 (see Fig. 4) which extend downwardlyfrom the cover plateto the top The plate forming the bottom ofth'e air passages is ridged asin the earlier described construction at 14 and the sections or ridgelikewise fall away in concave curvesformmg deflectors but draft issufficient rises along,

Wings 12',-13' upon optheir shape is modified to conform to the modifiedshape of the ventilator casing. this modification the screen 23 isarranged in a horizontal plane at a suitable distance above the ridge topermit some of the air entering the device spilling over the ridgewithout passing through said screen.

' As above stated the operation of this form of ventilator issubstantially identical with in Figs. 1, 2 and 3 strikes against thehorizontal screen and on passing therethrough is deflected by the coverplate 11 into the car. In this modification the damper 17 is shownlocated in the plane of the flange plate 8 or substantially in that ofthe outer wall of the roof and its position is regulated by a handle 24provided with a rack 25 and spring-pressed finger 26 which resistsmovement of the handle but permits it under suflicient pressure. 7 v

I claim:

1. An intake ventilator having a longitudinal passage open at both ends,an outlet passage in one of thejside walls thereof and a transversedeflecting abutment in the bottom of said passage.

2. An air intake. or ventilator having a longitudinal passage open atboth ends, a

transverse horizontal deflecting abutment v intermediate the ends of thepassage and an outlet opening in one of the side walls there ofintermediate the ends of the passage and above the abutment.

3. An air inlet or ventilator having a longitudinal passage open at bothends and an intermediate outlet in-one of the walls thereof, an abutmentintermediate the ends of the passage and adapted to deflect the enteringcurrent of air, and end walls or abutments projecting from the wallofthe passage opposite the first mentioned abutment and extending towardthe same.

4. A ventilator or air in et having a long1- tudinally extending passage0 en at both ends, and an inter-mediate outlet, a transextending upwardfrom the bottom of the passage and adapted to deflect of air, and endwalls extending downward from the top of the passage substantially tothe level of the top LEE P.
